Abstract: 1,062,055. Deflecting propulsive jets. SOCI•T• BERTIN & CIE. May 15, 1964 [May 17, 1963], No. 20369/64. Heading B7G. A device for deflecting the gases issuing from a jet propulsion nozzle comprises in combination a plurality of tubes which open into the nozzle interior near the exit cross-section thereof and which are each elongated to extend round a portion of the nozzle periphery, combustion chambers respectively connected directly to the tubes by short convergent duets and means for selectively supplying any of said combustion chambers with reagents. The nozzle 1 of a rocket, near its exit plane 1b, is formed with four slots or ducts 2 which each communicate through convergent-divergent passages with an auxiliary combustion chamber 5<SP>1</SP>, of segmental form (Fig. 2, not shown) and formed with end walls and sides 5b and dividing partitions 5a. Fuel is injected through orifices 7a, 7b from annular fuel tanks 9a, 9b under the control of electrically operated valves 8, the tanks being pressurized from nitrogen bottles 10. In operation valves 8 are actuated by a control signal to supply fuel to the appropriate combustion chamber 5 so that with small delay combustion takes place and stabilizes at a pressure for which the appropriate convergent-divergent passage is adapted, the resultant gases issuing from the corresponding slot 2 serving to deflect the jet from nozzle 1. In a further embodiment, instead of sub-divided segmental combustion chambers, a plurality of individual combustion chambers connect to a common collector for each slot 2.

Abstract: 121,476. Shearer, W. B. Dec. 10, 1917, [Convention date]. Torpedo boats.-Consists mainly in launching torpedoes under their own propelling-power from a flooded chamber in a torpedo boat. The torpedo boat shown comprises a chamber 1, Fig. 3, containing the propelling and controlling machinery and the person in charge, and a torpedo chamber 3 closed by a bow portion 5. The control chamber 1 is covered by a conical structure. 85, 86, 89 of steel with hinges at 88, 90. The torpedo chamber 3 is covered by a hinged deck 13 and contains bottom rollers 35 and a top hinged frame 20 with rails 29 for guiding the torpedo between them. Rails 38 extend beyond the rails 29 into the bow portion. The bow portion 5 is hinged at 80 ana is opened and closed by means of a link 61 connected to a rod 57, which is worked backwards and forwards by means of a nut 59<1> and handle 60. The opening of the bow portion floods the torpedo compartment 3, enabling the torpedo to start under its own power. When the bow portion is closed, the water in the torpedo chamber 3 is removed by bilges 95 which syphon the water out when the boat is in motion, or by a pipe 96 connected to a pump driven by the propelling-engine 2 of the torpedo boat. The torpedo, when locked agairst forward motion by the catch 42, is also checked against backward motion by a buffer 48 hinged to a bracket on a water-tight bulkhead 4 between the control chamber and the torpedo chamber. To permit, the hinged deck 13 covering of the torpedo chamber to be swung open, and the hinged guide frame 20 to be swung up to enable a torpedo to be loaded into the chamber 3. the rods 57, 47 are made with disconnectible joints 75, and the link 61 is made detachable from the rod 57. While the link 61 is uncoupled from the rod 57, the bow portion may be held closed by pinning another link 77 on the bow portion to a bracket 79 on the end of the deck of the torpedo boat beyond the hinged part of the deck. When not in use, this link 77 is swung forward and rests idly on the bow portion. The boat is balanced by air tanks 7, 8, Fig. 6, disposed along each side.

Title: Improvements in shock absorbers
IPC: F16F9/48
Filed: 1927-08-04
Abstract: 301,761. Macdonald, R. M. Aug. 4, 1927. Fluid - friction vibration - dampers.-In a double acting cylinder and piston device the area of the fluid transfer openings is diminished in proportion to the strength of shock. In the construction shown in Fig. 1, opposite ends of the cylinders are connected by ports c<1>, c<2> and a passage g in an auxiliary piston e. Springs f tend to retain the piston e in its central position from which it is displaced by excess pressure at either end of the main cylinder and when so disposed one of the conical needle valves h<1>, h<2> reduces the effective area of the passage g, the amount of reduction depending upon the pressure. Modified constructions are described which may form the piston or may be disposed in the piston or in a transfer passage in the cylinder wall.

Abstract: 920,765. Haymaking machines. C. VAN DER LELY N.V. June 16, 1959 [July 9, 1958], No. 20652/59. Class 6(3). A haymaking machine comprises a main frame having two parts pivoted together about a non-vertical axis, rake-wheels 2-5 being carried on the second frame-part so as to be adjustable relatively thereto for different haymaking operations the adjustment being effected automatically by moving the frame-parts relatively about the non-vertical axis. In Fig. 1, the two frame parts comprise a drawbar 18 and the frame-structure 10, 11 the latter being mounted on the former through a bearing 14, the axis of which constitutes the non-vertical axis. A shaft 15 is mounted in the bearing and is secured to a shaft 17 floatingly mounted coaxially in the drawbar 18. The drawbar is universally pivoted at 29 to a yoke 25 carried bv tractor hitch-links and is suspended from the yoke by a spring 30 the anchorage point being adjustable along the drawbar. The rakewheels are mounted on arms 6-9 pivoted at 12, 13 to two parallel beams 10, 11 to form a parallel-linkwork. One of the arms, 7, is attached by a link 34 to a fixed flange on the bearing 14, so that when the entire structure is lifted and turned over about the axis of the fixed bearing 14, the reaction is transmitted by the link 34 to the parallelogram links 10, 11, 69, to swing all the arms 6-9 about their pairs of pivots 12, 13 so that the rake-wheels take up positions perpendicular to the beams 10, 11, for tedding. In Fig. 5 the rake-wheels are mounted on vertical pivots on a zigzag beam 46 which passes through their centres, the beam being rotatable about the. axis of a drawbar 40 connected to the tractor by a yoke 54. A link 66 corresponds to the link 34 and the rake-wheels are interconnected for simultaneous adjustment by a rod 63 connected by links 64, 65 to each rake-wheel bearing. In Fig. 7, the interconnection comprises a fixed bevel gear 95 on the drawbar 80 meshing with a gear 94 on a shaft 91 extending along the zigzag frame 81 and engaging each rake-wheel bearing by a pair of skew-gears 92, 93. The tedding position of the rake wheels is shown at 103. In Fig. 10, the rake-wheels are carried by J- shaped frame-members 112, 113 on shafts 118, 119 pivoted by horizontal bearings 120, 121 on a frame-member 111, itself pivoted about an axis 139 on a drawbar 143. The drawbar 143 has a yoke 127 connected to hitch links and carries fixed sprocket-wheels 133, 134 which are entrained by chains 135, 137 passing around sprockets 136, 138 on the shafts 118, 119. Inversion of the beam 111 about the axis 139 inverts the J-shaped beams 112, 113 and positions the rake-wheels so that they no longer feed crop to one another, i.e. they ted the crop. Specifications 920,766, 920,767, and 920,768 are referred to.

[Class 39 (i)] An electron discharge device comprises a cathode 5, Fig. 1, control grid 6, screening or accelerating electrode 7, and electron collecting electrode 10, all these electrodes being surrounded by a substantially elliptical focussing electrode 13 ; the electrodes 5, 6, 7, 10 are disposed along the minor axis of the ellipse and do not extend beyond the limits thereof, and the device is operated so that electrons emitted from the cathode in divergent directions are caused to follow curved paths and to converge upon the collector 10. The focussing electrode 13 may be of sheet metal, or a mesh or wire-wound grid structure, or a series of rods ; when it is composed of a number of discrete parts gaps may be left between the parts provided the focussing field is not materially affected ; it is operated preferably at zero potential. Support rods for the electrodes 5, 6, 7, 10 may extend beyond the limits of the minor axis of the elliptical focussing electrode 13. In a modified construction the cathode 5 is emissive on one side only in which case the focussing electrode 13 is substantially semi-elliptical. The anode 10 may be secondary emissive, e.g. is coated with magnesium, a further collector electrode 11 of grid-like form being provided, as shown ; the electrodes 6, 7 may be wire-wound grids of elliptical form in cross-section. The cathode 5 and secondary emitter 10 need not be equally spaced from the centre of the minor axis of the elliptical electrode 13. A shield or shields may _be,disposed between the cathode 5 and secondary emitter 10 to shield the latter from material evaporated from the cathode, Figs. 3, 4, 5 (not shown), and the collector 11 may be of one or two flat or curved metal strips, Fig. 5 (not shown). If the anode 10 is not secondary emissive the electrode 11 is either omitted or used as a suppressor grid. Specification 545,803 is referred to. The Provisional Specification states in addition that the focusing electrode 13 may be operated at a negative potential and may be rectangular in shape.

Title: Improvements in or relating to winding coils
IPC: H01F41/04
Filed: 1947-07-31
Abstract: 651,399. Winding coils. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 31, 1947, No. 20728. Convention date, July- 31, 1946. [Classes 120(ii) and 120(iii)] [Also in Group XXXV] In a method of winding an electric coil comprising wire wound on a former, the wire or the former, or both, is provided with a dry coating of a thermo-setting adhesive, the former being then heated and the wire wound thereon whereby the adhesive is rendered tacky to cause the wire to adhere to the former. Kraft paper &c. coated with a thermosetting adhesive, e.g. a vinyl resin, is wound on to a split metal sleeve 2 which is placed upon an electrically heated arbor 3 rotated by a hand wheel 18 or by a belt 19 driven by an electric motor. A roller 4 carried by a, pivoted frame 5 is then urged by a handle 5a against the coated paper to bond the tacky layers together and with adhesive on the outer surface. Wires W<1>-W9 from braked spools S<1_>S<9> on a creel 7 are led around rollers R<1>-R<9>, thence about traversing- rollers M<1>-M<9> on a rod 8, traversed by a hand lever 8a, the ends being positioned under clips 9. carried by alternate abutment members F<1>-F<20> carried by a pivoted. frame 11. The wires, which are enamelcovered and preferably coated with a resinadhesive, are then attached to the tacky former and the frame 11 swung so that the abutments F<1>-F<20>, which limit the traverse, almost touch the former. The lever 8a is then manipulated to traverse the wires on to the former. When the required number of rotations has been effected, as shown by a counter 17, the operative pulls each wire over an abutment and positions it under a clip 9. The frame 11 is then forced by the operative away from the former and each wire is broken. The metal sleeve 2 is then removed from the arbor and the former removed therefrom by a pincer-like hand tool comprising a pin which can be engaged in a helical groove 3a in the arbor so as to force the former and sleeve therefrom. The former is then removed from the sleeve and placed in a conventional oven in order that the adhesive may be set. The wound former is then cut into discrete coils.

Title: Process for the recovery by distillation of the solvent used in the extraction of phenols from aqueous liquors
IPC: C01C1/10
Filed: 1952-08-19
Abstract: <PICT:0720341/III/1> In a process for the recovery of a solvent from a mixture of the solvent, one or more phenols and water, such as is obtained in the extraction of a phenol from an aqueous solution with an organic solvent which is immiscible or only partially miscible with water, the mixture is preliminarily heated up to a temperature greater than the boiling point of the solvent/water azeotrope but lower than the boiling point of the phenol, and is submitted to fractional distillation in a column so that there passes overhead a vapour mixture containing water and solvent but none of the phenol, while an anhydrous mixture of phenol and solvent is obtained as bottoms.  The bottoms are separated into phenol and solvent in a further fractionation stage.  Liquors from the low-temperature carbonization of lignite are dephenolized with butyl acetate; and the extract, which is a mixture of phenols, butyl acetate and water, is collected in vessel 2.  The extract is passed through pipe 4 to condenser 5, where it is preheated by the vapours issuing from column 9; and it is then passed through pipe 6 to evaporator 7, where it is raised to 130 DEG  C.  The mixture of vapour and liquid so obtained is passed through pipe 8 into bubble-cap column 9, the base of which is maintained at 175 DEG  C. by external heater 11.  A mixture of butyl acetate and water vapours, with only traces of phenols, leaves the head of the column through pipe 13 and is condensed in condenser 5.  The condensate is passed through pipe 14 to cooler 15 and the cooled condensate flows through pipe 18 to separator 19, where butyl acetate and water separate.  The water, which is withdrawn through outlet 20, contains a small quantity of butyl acetate and is passed to the column (not shown) in which the dephenolized liquor is stripped of solvent.  Butyl acetate is in part withdrawn through outlet 21 and is returned to the extraction plant.  Part of the butyl acetate is, however, returned as reflux to column 9 via pipe 22.  A mixture containing 50 per cent. of phenols and 50 per cent. of butyl acetate is withdrawn from the base of column 9 and is passed through pipe 24 to column 25, which is packed with Raschig rings and is heated by external heater 26.  The base of column 25 is maintained at 135 DEG  C. and the absolute pressure in the column is maintained at 50-60 mm. Hg. by means of steam-jet pump 28, which is connected to the head of the column via condenser 30.  The condensate from column 25, which contains 80 per cent. butyl acetate and 20 per cent. phenols, flows through barometric downpipe 31 and is mixed with the feed to column 9 in pipe 4. Phenol oil containing only 0.5 per cent. of butyl acetate is withdrawn via pipe 35 from the base of column 25, and is collected in tank 34.

IPC: B21B27/10
Filed: 1971-04-19
Abstract: 1287244 Rolling mills USS ENGS & CONSULTANTS Inc 19 April 1971 [18 Feb 1970] 21185/71 Heading B3M The rolls of a hot rolling mill stand are supplied with oil only during the passage of a workpiece through the stand. The supply of oil is made in response to the detection of the leading and trailing edges of a workpiece strip. The oil is sprayed on to the backing rolls of the stand by sprays 8 and 10 fed from a continuously running pump 18. A valve 20 directs the pump output either to the sprays or to a reservoir 14. When a workpiece strip 5 approaches the stand, a detector 28 causes a contact 32C to close, and when the strip passes the detector 26, the contact 30C closes. This operates a switch 20S to make the valve 20 direct oil to the sprays. Similarly, when the trailing end of the strip passes detector 28, the contact 32C closes and the valve 20 directs the oil to the reservoir. The oil is thus supplied only for the period between the leading end just passing the stand, and the trailing end nearly reaching the stand.
